[vtkusers] vtkSelection and vtkExtractSelected*

[John Norris]

Hi,

I've got a feature request regarding vtkSelection and the vtkExtract* 
filters that use it.  It would be really helpful if there was some sort 
of "ReverseSense" or "EverythingElseExcept" option, either as flags in 
the algorithms or as an information field in vtkSelection.  Basically I 
want to turn the selection list into an exclusion list.

I can make these changes myself; they're fairly straight-forward.  I'd 
be willing to contribute them if it something that Ken Martin, Will 
Schroeder, and Bill Lorensen deem valuable enough.

John
